Market context
Karmine Corp Blue’s LFL regular-season meeting with Skillcamp Esport is priced as a heavily one-sided contest in the live market, even though the current contract shows **0% YES**. That is a sharp divergence from sportsbook-style prices: Robinhood’s prediction market listed Karmine Corp Blue at **59¢** versus Skillcamp Esport at **32¢**, implying a clear favourite but not a shut-out. Stratified across comparable match pages, Karmine Corp Blue also carried the stronger pre-match profile in the spring meeting, and the same pairing has already gone Karmine Corp Blue’s way once this year, 1-0, in April.[2][9][11]
The historical frame is important because BO1 League of Legends markets are volatile, and recent form can move prices quickly if rosters or schedules change. Karmine Corp Blue’s prior win over Skillcamp, plus its stronger standings at the time of the spring clash, explain why traders have tended to favour KCB in similar listings, while third-party match pages still treat the fixture as live and unresolved with no consensus prediction posted on some platforms.[2][3][4] The present 0% reading therefore looks more like an artefact of contract pricing or thin participation than a clean view of competitive balance.[9]
For traders, the key catalysts are straightforward: confirmation that the match actually starts on the scheduled LFL summer slot, any late schedule movement, and final lineup news before lock. Multiple fixtures pages place the game on 6 August in a BO1 regular-season format, with the listed start time varying between 17:00 UTC and 20:00 UTC across aggregators, so the practical risk is procedural as much as competitive.[1][3][6] If the match is delayed beyond the market’s seven-day settlement window, or not completed after starting, the contract rules point away from a standard win/loss resolution and towards the fallback outcome specified in the market terms.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
